Toyota Repair: 91 toyota camery, break pads, fuel line

Question
i have a 91 toyota camery 4 cylinder stick. my car was running fine and then i put some break pads on the font, and now its wont start. the engine still turns and still gets spark and fuel. any clue what the problem is?

Answer
WOW thats an odd one.
did you jack it up and hit something underneath by accident, like a fuel line?
Did you do anything else?
Where you under the hood at all?

Really no reason for this to be connected,

Did you check for spark at the plugs?.
